Getting the right oil for your car is one of the things that make your vehicle last longer. Before you use any engine oil, it is always advisable to look at the car’s manual.

The manual shall list the recommended oil weight. The viscosity of the oil shall also depend on the seasons and also the expected car usage. It is vital to consider choosing an oil from a brand that displays a symbol that proves that the oil you intend to apply has been tested by the famous American Petroleum Institute (API).

For reputable motor oil, there are different labels that you are likely to see on every container. The American Petroleum Institute doughnut marked on the right shall tell you if that oil meets the service rating. The same oil shall also meet the Society of Automotive Engineers (SAE) viscosity numbers and advise if it has passed the expected resource-conserving tests. The symbol on the left shows that the oil has passed every service test listed on the other doughnut.


Oil viscosity refers to the fluid’s resistance to flow. The motor oil’s viscosity is usually rated based on its thickness at zero degrees Fahrenheit.

The engine oil becomes faster and thinner as it heats up. When it cools, it starts to thicken. The thicker oil always maintains better lubrication between the car moving parts and is also entrusted in sealing the engine’s vital components.

During low temperatures, oil is always resistant to thickening and flowing correctly in all engine moving parts. The excess thickness makes it difficult to start the car engine. If the motor oil is thought, the engine may need more energy to turn the crankshaft.

Therefore, a 5W type of oil is better during winter seasons. However, the synthetic oils are designed to flow easily when it is cold and thus pass the OW rating.

The auto parts stores have oils designed for all specific purposes. In these oils, you shall notice a wide selection of effective viscosity.

Choosing Between Synthetic and Conventional Motor Oil

Conventional Motor Oil: This type of oil is the standard car oil, and mostly you will find the oil in all the leading brands. The oils are available in several viscosity and are also tested under the current API levels. For colder temperatures, the auto experts recommend 5W-20 and 5W-30 oil. Those in higher temperatures are advised to use 10W-30 oil. The above ratings are for light-duty cars.

Most importantly, it is recommended to ensure that we change the oil every 4,000 miles or after four months. Some cars have been fitted with electronic oil change indicators on the instrument cluster. It is essential to follow the guidelines and reset them once the oil change has been done.

Full Synthetic Oil: Synthetic oils made for heavy-duty usage. They have been designed with several additives. They indicate whether they have passed the tests for more extended lasting performance from the viscosity percentage to protection against all the deposits. They flow better at a lower temperature as well as maintaining peaking during higher temperatures. The oils are also expensive and not for every engine. There are features that your car engine may need that the synthetic oil may not have. It is, therefore, important to consider following the owner’s manual.

Synthetic Blend Oil: The oil has a dose of synthetic oil mixed with organic oil. They have been formulated to protect heavier engine loads and also higher temperatures. They are less volatile and evaporate far less, reducing oil loss and even increasing fuel economy. Most pickup owners and SUVs use these oils for extra protection for the activities that put more stress on the car’s engine. They are cheaper than full synthetics.

Higher Mileage Oil: Modern vehicles usually last longer. If you pay your car and run the mileage better into the six figures, you may have another oil choice. The oils are formulated for high mileage vehicles.
